STRUCT MPI3MR_STGT_PRIV_DATA(9)

💅 struct mpi3mr_stgt_priv_data 💅

okay so bestie, welcome to the Kernel API Manual ✨ this is the page for struct mpi3mr_stgt_priv_data and honestly it's giving "behind-the-scenes queen of the SCSI target world" 👑

---

🌸 NAME 🌸

struct mpi3mr_stgt_priv_data — the SCSI target private structure, no cap 💖

---

✨ SYNOPSIS ✨

literally the whole shape of her, character for character, don't touch:

struct mpi3mr_stgt_priv_data {
    struct scsi_target *starget;
    u16 dev_handle;
    u16 perst_id;
    u32 num_luns;
    atomic_t block_io;
    u8 dev_removed;
    u8 dev_removedelay;
    u8 dev_type;
    u8 dev_nvme_dif;
    u16 wslen;
    u8 io_throttle_enabled;
    u8 io_divert;
    struct mpi3mr_throttle_group_info *throttle_group;
    struct mpi3mr_tgt_dev *tgt_dev;
    u32 pend_count;
 };

🎀 Members 🎀

bestie, this is the group chat roll call, every single one of them gets an intro 🫶

• starget — the Scsi_target pointer. like, her link back to the scsi_target she belongs to 💫
• dev_handle — the FW device handle 🔥 (FW = firmware, iykyk)
• perst_id — the FW assigned Persistent ID, iconic and permanent 💅
• num_luns — the Number of Logical Units 🌸
• block_io — whether I/O is blocked to the device or not 🚫 (drama!)
• dev_removed — Device removed in the Firmware 💀
• dev_removedelay — Device is waiting to be removed in FW, she's on the waitlist 🙈
• dev_type — Device type, main character categorization 👑
• dev_nvme_dif — Device is NVMe DIF enabled ⭐
• wslen — Write same max length 📏
• io_throttle_enabled — I/O throttling needed or not 🐢 (sometimes you gotta slow down, bestie)
• io_divert — Flag indicates io divert is on or off for the dev 🔀
• throttle_group — Pointer to throttle group info 🎀
• tgt_dev — Internal target device pointer 🦋
• pend_count — Counter to track pending I/Os during error handling 😭 (error handling era fr fr)
